VALENCIA, Calif.—(BUSINESS WIRE)—Dec. 5, 2005—
3D Systems Corporation (Nasdaq:
TDSC), a leading provider
of rapid 3-D printing, prototyping and manufacturing solutions,
announced today the introduction of DuraForm(R) EX plastic, a new,
advanced, engineered, production-grade plastic for rapid
manufacturing. The company plans to offer DuraForm EX plastic for use
in its new Sinterstation(R) Pro SLS(R) systems during the first
quarter of 2006 and to make it available for use in its Sinterstation
HiQ(TM) SLS(R) systems in the second half of 2006.

"This revolutionary new product is exactly what the rapid
manufacturing industry has been waiting for," said Abe Reichental, 3D
Systems' President and Chief Executive Officer. "In fact, DuraForm EX
plastic is the first rapid manufacturing material to offer the
toughness and impact-resistance found in injection molded plastics.
Its outstanding combination of performance characteristics makes
DuraForm EX ideal for advanced functional prototyping, rapid
manufacturing applications and end-use parts.

"Expanding our portfolio of customer-driven manufacturing
solutions continues to be a top priority for us," continued
Reichental. "DuraForm EX plastic reflects our ongoing commitment to
listen to our customers, capture and to translate their specific
requirements into a production-grade material that meets their
manufacturing needs. DuraForm EX plastic provides the toughness of
injection-molded plastic that our aerospace, automotive and
motorsports customers require for demanding prototyping and low- to
mid-volume manufacturing applications. Because of its stiffness,
heat-resistance, long-term stability and durability, DuraForm EX is
ideal for a wide variety of parts manufacturing, including
environmental ducts, electronics enclosures, manifolds, dashboards and
bumpers.

"We are very excited to deliver this advanced manufacturing
material for our Selective Laser Sintering product line. This is
another significant building block in our comprehensive strategy to
advance the state of rapid manufacturing by providing new and
innovative solutions to replace and displace today's traditional
manufacturing methods," concluded Reichental.
